When an MMIOFlip's FlipEntryStatusAfterFlip is FlipWaitHSync, PresentMon will wait until an HSync DPC event comes in before considering the frame completed, which enables for more accurate timing than just assuming it completes immediately. However, an HSync is still a tearing Present, while PresentMon currently treats it the same as a VSync, which is non-tearing. We should track this metadata correctly.
